New generation of PET thermoforming sheet lines

Following
the success of the 2013-release high-performance extrusion lines for PET
thermoforming sheets with the patented mechatronic polishing stacks of the Mirex-MT-V
design series, the next generation of this line type was presented this year.

As in the
past, the heart of these lines is the tried-and-tested synchronous “REItruder”
twin-screw extruders, which are now in their third generation. In combination
with dry-running high-performance vacuum pumps that work with an operating
pressure of 5 mbar, and the degassing units on the REItruder that have
continuously been optimized through the years, the systems meet the FDA
requirements for films that are made of 100% recycled PET and are in direct
contact with food. All required declarations confirming the line technology's
compliance with EFSA requirements are provided; the user is responsible for
applying for the appropriate EFSA approval.

Depending
on the customer's requirements, various different coextrusion feedblocks are
available from Reifenhäuser EDS, the youngest member of the Reifenhäuser Group.
The customers have frequently expressed their desire for simple (quasi “plug
and play”) production. To meet this need, feedblocks are now available both for
fixed layer geometries and for the tried-and-tested and highly flexible
REIcofeed 2.1 systems that can be configured during operation. Additionally,
completely modernized dies are available in the wide product portfolio of
Reifenhäuser EDS. For example, the producer can choose between internal
deckling for maximum flexibility in the film width, or a lip gap that can be
configured during operation for fast thickness changes, as well as between
manual or automatic operation with thermal expansion bolts.

After 5
years of successful worldwide use, the Mirex-MT-V high-performance polishing
stack has also been fundamentally modernized. Depending on the system capacity,
it has 3 or 4 polishing rolls. Additionally, an axis crossing for the first
roll is available optionally, for the production of thin films with large
widths.

The
entire line has been prepared for the implementation of Industry 4.0 functions
that are being developed group-wide by Reifenhäuser Digital. Thanks to the
modular concept, the customers can decide individually which functionalities
benefit their business activities and which are not needed (for the time
being). The tailor-made solutions for individual needs are part of the
portfolio of Reifenhäuser CSC, from “as simple as possible” to convenient fully
automated solutions.
